FREDERICK (ANNING SCHMIDT, OF NE\V YORK, N. Y.

PAVEMENT.

SPECIFICATION forming part of Letters Patent No. 442,784, dated December 16,1890.

Application filed May 15, 1890. Serial No. 351,906. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK CANNING SCHMIDT, of the city, county, and State of New York, have invented a new and Improved Pavement, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved pavement which is simple and durable in construction, can be very readily laid, and prevents sagging of the pavingblocks.

The invention consists in certain parts and details and combinations of the same, as will be described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of the improvement as applied. Fig. 2 is a longitudinal section of one of the plates and its supports, and Fig. 3 is a plan view of one of the supports.

The improved pavement A is provided with plates B, preferably made of cast metal, of suitable sizes, and having on top transverselyextending ribs 0, placed equal distances apart and arranged parallel, as is plainly shown in Fig. 1. The parallel ribs 0 thus form continuous channels D, in which the pavingblocks E are set one alongside the other, the several rows being divided by the thin wed geshaped ribs O.

011 the ends of each plate B and on its under side are secured downwardly-extending flanges F, adapted to pass into channels G, formed in the tops of supporting-beams 11, adapted to be laid on the ground and pro- Vided with beveled ends I, so as to permit of readily joining several beams to form a frame or support for all the sides of the plate. The channels G are sufficiently wide to admit two flanges F of adjoining plates, so that several plates are connected with each other by the respective supporting-beams II.

In order to lay the pavement I proceed as follows: The ground is first put in the proper condition to receive the beams H, which are placed on the ground so as to form rectangular frames, the beveled ends I adjoining each other, as is plainly illustrated in Fig. 1. A plate B is then placed in the first frame formed by the beams I-I so that its flanges F pass into the channels G and the ribs 0 extend transversely across the street. B is then placed alongside the first plate on the next frame of beams so that the ribs 0 are in line with the ribs of the first plate. This operation is repeated until the plates are laid from curb to curb, so that continuous channels are formed from one side of the street to the other by the parallel'ribs of the several plates. A similar row of plates is placed on the next following frame of beams II, so that finally the street is covered with plates B in the mannerpreviously described. The paving-blocks are then placed into the continuous channels D, and the intervening spaces between the rows of blocks may be filled in with suitable material, such as sand, gravel, asphaltum, &c.

No spaces need be formed between adjoining paving-blocks in one of the channels; but they may be separated, if desired, and the space filled in with sand, asphaltum, &c.

It will be seen thata pavement thus formed is very durable in construction and can be very readily and quickly laid at a small cost, no skilled labor whatever being required. It will further be seen that, as the pavingblocks are supported on solid plates which in turn have a good foundation, the pavingblocks are not liable to sag, as is so frequently the case in pavements as now constructed.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a pavement of the character described, the beam II, having a groove G from end to end on its upper side and having its sides beveled at both ends, as shown at I, substan tially as set forth.

2. In a pavement, the plate 13, having blockreceiving channels on its upper side and a marginal flange F depending from each of its several side edges, substantially as set forth.

3. In a pavement, the combination, with four beams II, beveled, as shown at I, and each having a groove G on its upper side, extending from end to end to form a continuous rectangular channel, of the plate B, having A plate B, placed side by side across the street and having depending marginal flanges around 7 their four sides entering the rectangular channels formed by the grooves G, the upper face of each plate having a series of parallel ribs, the ribs of the several series being in alignment and forming parallel transverse blockreceiving channels, substantially as set forth.
